Conciseness

The body is lean and directive — no explanations of concepts Claude already knows, every line carries instructions (e.g. "do not patch a skill for a runtime permission failure", "Never persist credentials, customer identifiers, raw incident logs"). It misses a 5 because of tokens that earn no place: the empty "**Priority: P1 (HIGH)**" heading and the vague "Canonical response anchors" section add bulk without actionable value.

Actionability

The protocol gives concrete, executable guidance: exact fields to record ("skill ID, indirect phrase used, and fix (add keyword alias to triggers)"), concrete statuses ("status `proposed` until independently reviewed") and a defined output block with its schema deferred to references/methodology.md. Not a 5 because no worked example or filled-in trigger-miss record appears inline or is quoted in the body, leaving minor gaps for first-time execution.

Workflow Clarity

The eight-step Protocol is a clearly sequenced process with explicit validation checkpoints and feedback loops: "Evaluate — Compare candidate with current guidance and no-skill baseline on held-out cases", "Require independent maintainer approval", and the guideline "Stop on missing proof: Missing approval/evals leaves candidate unpromoted" with a canary/rollback path. This matches the top anchor of sequence plus explicit validation and recovery.

Progressive Disclosure

The body is a concise overview with a structure tree showing the single bundle file, and the detail (signal tables, taxonomy, report template, trigger-miss schema) is appropriately deferred to one-level-deep references at references/methodology.md, which exists and contains exactly that deferred content. Both mention sites use clear anchored links, matching the top anchor.

Specificity

The description lists several specific actions — "Review session corrections, trigger misses and recurring agent mistakes to propose targeted skill-library changes" — naming concrete objects (corrections, trigger misses, recurring mistakes) and a concrete output (targeted skill-library changes). It falls short of a 5 because the action verbs are few (review, propose) and the phrasing is jargon-dense rather than plainly concrete.

Completeness

It explicitly answers both: what it does ("Review session corrections, trigger misses and recurring agent mistakes to propose targeted skill-library changes") and when to use it ("Use for retrospective, rework or routing-gap analysis before registry edits"), plus an explicit loading instruction. Both halves are concrete and clearly stated, matching the top anchor.

Trigger Term Quality

"Use for retrospective, rework or routing-gap analysis" includes natural user phrases like "retrospective" and "rework", giving good coverage. Not a 5 because common synonyms such as "post-mortem", "session review" or "skill feedback" are missing, and "routing-gap analysis" is jargon a user would rarely say.

Distinctiveness Conflict Risk

It occupies a clear niche (skill-library maintenance retrospectives before registry edits) with triggers unlikely to fire for unrelated skills. Minor overlap risk remains with generic code-review or learning/feedback skills, so it does not reach the fully distinct top anchor.
